Can English 18 Year olds (Near 19) get into clubs with hand stamps?
Nope to all. Vegas requires you to be 21 to get into the bars and clubs, and they are very strict about checking ID’s. There are no hand stamps in Vegas. Also, they are very good about catching fake ID’s, so I don’t think your old passport will pass their inspection either. You can try, and they will probably just deny you entry into the club. But they have the right to call the police and have you arrested, and I have seen it happen before. Better to choose a different vacation spot if you’re dead set on partying with your friends. Or be happy to find something else to do in Vegas while they’re out at the clubs.
